They show the subject line and body too.  I still don't understand
why it's vital to vet the From: line but not the rest of the message.

This appears to he be same old wrong idea about DKIM that the d=
domain has some mystical connection to the From: line or other domains
in the message.  It doesn't.  If you disagree, please point to the
relevant language in RFC 6376.
